Urine Mass Concentration of Creatinine

Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms of kidney problems, such as swelling, fatigue, or changes in urine output. It may also be used during routine check-ups, especially if you have conditions like diabetes or high blood pressure that can affect kidney health.

How Is the Test Performed?

You will collect a sample of your urine in a clean container. The sample is then sent to a lab for testing. No special preparation is usually needed, but you may be asked to avoid certain foods or medications for a short time before testing if instructed by your provider.

What Do the Results Mean?

The results help determine how much creatinine is present in your urine, which can indicate how efficiently your kidneys are working. Higher than expected levels might suggest kidney issues, while lower levels could indicate dehydration or other conditions affecting urine concentration.

What Are the Possible Causes?

Elevated urine creatinine levels may be linked to kidney disease, dehydration, or conditions that reduce blood flow to the kidneys. Lower levels might be due to excessive fluid intake or certain medications.
